The impeachment filings allege Nixon acted outside the bounds of the state constitution by allowing same-sex tax filings, though the governor said he was simply complying with a federal decision.

"Impeachment is the only option available to us," Rep. Mike Moon (R-Ash Grove) said.

Moon submitted one of the three filings. His document alleges the governor took too long to set up elections that would replace vacant seats in both state houses. Another filing claims the governor failed to act or discipline anyone for the release of information regarding conceal and carry applicants.

Moon said it's "anybody's guess" whether the filings will go any further.

"It's clearly a political decision that gets made but it's not inappropriate considering the way the state government, and the federal government for that matter, are set up," Dr. Brian Calfano, a Missouri State University political science professor, said.

Calfano said whether or not the impeachment advances, the Republican representatives who filed them have already sent their message.

"It gets these grievances up on the board if you will," Calfano said.

Moon said that while lawmakers' time is limited, with less than three weeks left in the current session, he thinks the impeachment filings deserve the full legislature's attention and consideration.

"I appeal to you that there is no more important matter than giving all the people of Missouri a voice and there have been over 200,000 people unrepresented this entire legislative session," Moon said.

Calfano said other topics will likely take up the legislature's time, until it adjourns on May 16.

"The biggest issue at this point is going to be the big income tax cut and what's gonna happen with he bill -- certainly facing the governor's veto, and if there's going to be an override," Calfano said.
